• n=1–12 in task group 1
• n=13–24 in task group 2
• n=25–36 in task group 3
The task time defines the execution repetition rate, and is 1, 3 or 8 respectively for
the three task time groups.

Figure 286: SMAI2 function block
Figure 286 is an example of SMAI2:n to SMAI12:m in each of the three task time
groups 1, 2 or 3 where:
• n=2 and m=12 in task group 1
• n=14 and m=24 in task group 2
• n=26 and m=36 in task group 3
The task time defines the execution repetition rate and is 3, 8 or 1 ms, respectively,
for the three task time groups.
